Hundreds of millions of tons of plastics are produced each year. Millions of those tons enter our air, soil, and water as waste. As waste, some of this material–still many millions of tons–breaks down into smaller particles, or microplastics (< 5 mm in size); microplastics come from many sources including the manufacture of industrial products and the physical, chemical, and biological breakdown of larger pieces…

See moreNews: Misuse and overuse of antibiotics with farm animals (especially to promote growth) and with humans “is a main reason behind [the] evolution of antibiotic resistant pathogens.” This is an increasing threat to human health–in both poor and rich countries. However, other accumulating pollutants in our environment interact to make the problem bigger and make it worse. Metals–like mercury, lead, zinc, copper, and cadmium–accumulate to…
